Creating these delightful Soft & Fluffy Banana Muffins is a breeze when you follow these step-by-step instructions:

1. Preheat your oven: Set your oven to 350°F (175°C) and line a muffin pan with muffin liners or grease it lightly.
2. Mash the bananas: In a large mixing bowl, mash the ripe bananas with a fork until smooth.
3. Mix in melted butter: Stir in the melted butter until well combined.
4. Add baking soda and salt: Sprinkle in the baking soda and salt, and mix to incorporate.
5. Combine sugar: Stir in the sugar until well blended.
6. Add the egg: Mix in the beaten egg thoroughly.
7. Incorporate vanilla: Add the vanilla extract and go for another good stir.
8. Fold in the flour: Slowly add the all-purpose flour, stirring until just combined. Do not overmix; a few lumps are okay.
9. Pour into muffin tins: Distribute the batter evenly across the muffin cups, filling each about 3/4 full.
10. Bake: Put the muffin pan in the oven and bake for 18-22 minutes, or until a toothpick inserted into the center comes out clean.
11. Cool down: Remove from the oven and let them cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely.

These simple steps will guide you in creating Soft & Fluffy Banana Muffins that are heavenly and moist.
